Accidentally Saving The Bees
There is no shortage of dangers to honey bees, but a parasitic mite known as Verroa destructor is considered to be the greatest threat because it transmits virus diseases which lead to colony death.
Trends Influencing Our Cities
The Environmental Protection Agency removed its information hub about climate change last year. In response, 17 cities reposted the information on their own city government sites. This is indicative of the fact that cities are increasingly taking on a leadership role in environmental, social and economic change.
Disappearing Kelp Forests
In recent decades, ocean temperatures in many places have warmed by nearly 3 degrees Fahrenheit. An effect of this warmer water is the decimation of what were once luxuriant giant kelp forests in eastern Australia and Tasmania. There used to be thick canopies covering much of the region’s coastal sea surface, but they have wilted in the intolerably warm and nutrient-poor water.
An All-Electric Plane
The British discount airline EasyJet recently announced a partnership with American company Wright Electric to develop an all-electric commercial airplane that they said could be flying within 10 years. The goal of the partnership is to develop aircraft with a maximum range of 335 miles, which is long enough for many of the European routes that EasyJet flies from its hub in England.
Looking For “Super Coral”
Coral reefs are essential for much of marine life and are the basis of many commercial fisheries. In places from Florida to Australia, they are major tourist attractions. Estimates are that the economic impact of coral reefs is more than $375 billion a year. And apart from all of that, they are some of the most beautiful places on the planet.
Saving Chocolate
On previous occasions, we have talked about the problems faced by the global banana industry, which is based almost entirely on a single cultivar, the Cavendish banana, which makes the industry extremely vulnerable to a single disease or blight that may arise.
Offshore Wind Progress
Last December, the first commercial offshore wind farm in the United States started operation off the coast of Rhode Island. The Fisherman’s Energy Atlantic City Windfarm off the coast of New Jersey is under construction. With the lengthy logjam finally broken, there is increasing activity in the emerging U.S. offshore wind sector.
An Aluminum Battery
The battery industry is currently dominated by lithium-ion batteries. We have them in our phones and computers. They power electric cars. And they are increasingly being used to store energy generated by solar panels and other renewable energy sources.
Delivery By Fuel Cell
UPS recently announced a demonstration project that will put a prototype electric truck powered by a hydrogen fuel cell through the delivery company’s challenging paces. Fuel cells have been used in some commercial vehicles to power auxiliary systems, but this is the first time that they will be used to propel a vehicle.
Spray-On Solar Cells
One of the most exciting possibilities for future solar energy technology is that of solar cells that can be sprayed or printed on to surfaces like the windows of skyscrapers, the roofs of sports utility vehicles, or the walls of houses. And the expectation is that such technology would be far cheaper than today’s silicon-based solar panels.
DNA Analysis of River Water
DNA analysis has become commonplace and inexpensive. Millions of people have their DNA tested to learn about their origins and family connections. And the technology has spread to biological research in the form of Environmental DNA or eDNA, which is such a powerful tool that it is transforming the field of wildlife biology.
A Soy-Based Air Filter
Particulate matter and toxic chemical pollutants are a pervasive problem in the air people breathe in many places. Poor air quality causes health problems worldwide and is a factor in diseases such as asthma, heart disease and lung disease.
Spider Silk
Spider silk – the protein fiber spun by spiders to make webs, nests, cocoons, and wrapping for prey that they stash away – is a remarkable substance. Its mechanical properties combine high tensile strength and high extensibility or ductility. This allows spider silk to absorb a lot of energy before breaking. It is stronger than steel, but not as strong as Kevlar, for example. On the other hand, it is tougher than either.
Giant Wind Turbines
Wind turbines have been getting bigger and bigger over the years. The reason is that bigger blades produce more power and give much more bang for the buck. A big part of the plummeting price of wind power is the increasing amount of power produced by each turbine.
Arctic Shipping
The Arctic used to be pretty much a pristine wilderness populated only by fairly small numbers of indigenous residents living environmentally benign lifestyles. The disruptive elements of modern civilization were not much of a factor. Because of the changing climate, this is no longer true.
Help Save The Bees
Globally, 40% of invertebrate pollinator species, such as bees and butterflies, are facing extinction. And since approximately three-quarters of the world’s food crops depend on pollination, the decline of these pollinators could pose a threat to food security around the globe.
Saving the Banana
Bananas are the world’s most popular fruit crop, with 130 countries producing over 100 million tons annually. Forty-seven percent of all the bananas grown in the world and ninety-nine percent of all the bananas sold commercially are of one subspecies known as the Cavendish.
One Million Roofs
Sometime early in May, the United States installed its one millionth solar energy system. Achieving this milestone took the solar industry about 40 years to accomplish. Because of the phenomenal growth of solar power in this country, industry experts predict that it will only take two more years to reach the second million and there are predictions that by the year 2025, there will be one million new installations in the U.S. each year.
Businesses Going Solar
The fourth annual Solar Means Business Report is out. It identifies major commercial solar projects and ranks America’s top solar users. Just since the first report came out, the amount of solar power installed by America’s top companies has tripled.
